基于 SagerNet/sing-box-for-android 的非官方 Android 客户端，使用 FlClash v0.9.2 的 Flutter 界面组件，后端保持 sing-box。项目独立维护，不代表两个上游的官方发布。
下载 APK：GitHub Releases（Android 7.0+，ARM64）。newui 的新界面与功能仍按提交验证；已有 Release 不等同于当前源码。
- Flutter 负责仪表盘、代理、配置、工具及所有子页面；启动器和 Android 分享入口均进入新界面。
- 配置使用 sing-box JSON。代理组、可选节点、测速和路由模式来自 libbox，自动组由内核选择。
- 保留 VPN、分应用代理、Root/Shizuku 应用查询、远程控制、连接管理和日志。
- 工具中的“请求”支持本地 HTTP/HTTPS 调试、域名筛选、请求详情及 HAR/cURL 导出，提供调试 CA 与 CertBridge 管理；支持范围和限制。
- Tailscale、Taildrop、SSH、OpenConnect/OpenVPN 认证、USB/IP、网络诊断和报告通过新页面使用现有后端。
- 支持配置和设置备份；B-box 既有包名、数据库及配置保持兼容。
- 旧 Compose 页面、导航、编辑器及更新下载/静默安装链路已移除。关于页使用独立的 B-box Release 检查；配置订阅更新继续保留。
- Xposed/LSPosed 和 Android 5/6 支持已移除。
